Samsung allegedly demoed its foldable phone to select audiences at CES 2019, said the Korean Herald.

In its coverage, Korean Herald reported that Samsung demonstrated its foldable phone to a few of its customers, marking the first time Samsung has showcased a working product to anyone after its press conference in November 2018.

A high-level executive of Samsung customer who saw the phone said that it’s close to release and that it’s currently going through the optimization stage.

“When unfolded, Samsung’s foldable phone does not show any crease indicating it had been bent, however, completely folding the device will lead to a breakage. For this reason, Samsung is testing out the device so that the sides remain slightly lifted when folded. The prototype seen today leaves a crease mark when being folded, but this issue will be fixed in the finalized version,” said the Korean Herald’s source.

The Samsung foldable phone is expected to feature a flexible main display on its interior and a smaller display used to check for notifications when the phone is folded.

While it doesn’t yet have an official name, the new foldable Samsung phone is expected to sell for around $1,700 due to its complicated design. Samsung has also stated its Galaxy 10 series will still be its main driver, and that it’s planning to manufacture smaller quantities of the foldable phone.

Several publications also believe that Samsung will launch its full lineup at its February 20 event in San Francisco.
